IN'KING ROLLER.

yppucwmm mea August '6, 1924. serial No. 730,419.

To all 'whom t may concerm v Be it known that JAMES F2 PERKINS, acitizen of the United States, residing at Hayward, in the county ofAlameda and State of California, has invented certain new and usefulImprovements in Inking Rollers, of which the following is aspecification.

' My invention is an improved inking roller.

The object o f my invention is to provide an inking roller, which may becontinuously fed with additional ink, as required, without removing theroller from the machine.

A further object of my invention is to provide an inking roll` which isadapted to be rotated by a rinting roll or platen and in which theinklng roll is mounted on dead centers and has ink fed through one ofthe dead centers into the` interior of the roll from which it depressesthrough a platen to the inking surface.

In the annexed ldrawing in which the preferred form of my invention isillustrated:

Figure 1 is a side view of my inking roller.-

Figure 2 is a longitudinal sectional view of the same.

Referring more particularly to the drawing, my inking roller comprises apair of heads 1 and 2, which are'journaled upon pin bearings 3 and 4respectively. These pins are preferably threaded into the frame members5 and 6,4t0 support the roller, andk also provide an adjustment forwear.

A perforated cylinder 7 is mounted between the heads l and 2, and may beeither secured lto said heads, or -formed integral therewith. A feltorsimilar fibrous pad 8 surrounds the cylinder 7, and a cloth strip 9surrounds the pad 8 against 4which the printing rolll() presses. A

A tube 11 extends through the pin 4, and

head 2, into the cylinder 7, and a suitable container, such as the cup12, is secured to sald tube above the level of the inking roll.4 Thusthe ink placed in the cup is fed by gravityto the perforated cylinder 7,from whence it is evenl distributed through the perforations thereln tothe pad 8 and thence to the cloth cover 9.

A stopper 13 is provided in the tube 11 at the outlet of the cup 12,which is controlled by a handle 14 extending through said cup. A valve15 is also provided in the tube 11 to stop the ow of ink therethrough.

It will be notedlthat the pinxgbearings 3 and 4 form conical dead centehich engage in the cones on the head and 2 of the roll, the ink carryingtube passing completely through the bearing 'pin 4 and the cone on thehead 2 does not retard the rotation of the roller. By means -of the feedsupport of the bearingpins 3 and 4 in the free members 5 and 6 4africtional resistance can be made against the cones of the heads l and2in order to partially retard o-r free the rotation of the inking roll.

Having described my invention, I claim:

1. An inking roller comprising in combination a pair ofheads each havinga coned bearing surface, a erforated cylinder between said heads, albrous pad surrounding the cylinder, stationary screw threaded bearingpms having conlcal ends engaging the coned bearing heads, a tube passingthrough one of the bearing pins and through one of the heads, andmeans-to feedv ink ,through the said tube.

2. An inking roller as claimed in claim 1. having in addition screwthreads on the bearing pins, and a frame in which said pins areadjustable to increase or decrease the .frictional resistance of therotation of the roller.

In testimony whereof I atx my signature.

' JAMES F, PERKINS.
